HughPickens.com writes According to an op-ed by Fareed Zakaria in the Washington Post, if Americans are united in any conviction these days, it is that we urgently need to shift the country's education toward the teaching of specific, technical skills, expand STEM courses (science, technology, engineering and math) and deemphasize the humanities. "It is the only way, we are told, to ensure that Americans survive in an age defined by technology and shaped by global competition. The stakes could not be higher." But according to Zakaria the dismissal of broad-based learning, however, comes from a fundamental misreading of the facts — and puts America on a dangerously narrow path for the future.

As Steve Jobs once explained "it's in Apple's DNA that technology alone is not enough — that it's technology married with liberal arts, married with the humanities, that yields us the result that makes our hearts sing." Zakaria says that no matter how strong your math and science skills are, you still need to know how to learn, think and even write and cites Jeff Bezos' insistence that writing a memo that makes sense is an even more important skill to master. "Full sentences are harder to write," says Bezos. "They have verbs. The paragraphs have topic sentences. There is no way to write a six-page, narratively structured memo and not have clear thinking." "This doesn't in any way detract from the need for training in technology," concludes Zakaria, "but it does suggest that as we work with computers (which is really the future of all work), the most valuable skills will be the ones that are uniquely human, that computers cannot quite figure out — yet. And for those jobs, and that life, you could not do better than to follow your passion, engage with a breadth of material in both science and the humanities, and perhaps above all, study the human condition."

schwit1 writes The May 6 Atlas 5 launch will carry one of the Air Force's two X-37B mini-shuttles on a new mission in space. "The Air Force won't yet confirm which of the Boeing-built spaceplanes will be making the voyage. The first craft returned in October from a 675-day mission in space following a 224 day trek in 2010. OTV No. 2 spent 469 days in space in 2011-2012 on its only mission so far. "The program selects the Orbital Test Vehicle for each activity based upon the experiment objectives," said Capt. Chris Hoyler, an Air Force spokesperson. "Each OTV mission builds upon previous on-orbit demonstrations and expands the test envelope of the vehicle. The test mission furthers the development of the concept of operations for reusable space vehicles." There are indications that the Air Force wants to attempt landing the shuttle at Kennedy this time.

sciencehabit writes: Stark and rising inequality plagues many countries, including the United States, and politicians, economists, and — fortunately — scientists, are debating its causes and solutions. But inequality's effects may go beyond simple access to opportunity: a new study finds that family differences in income and education are directly correlated with brain size in developing children and adolescents. The findings could have important policy implications and provide new arguments for early antipoverty interventions, researchers say.

knwny points out this lofty proposed power plan in China. "The battle to dispel smog, cut greenhouse gases and solve the energy crisis is moving to space. If news reports are to be believed, Chinese scientists are mulling the construction of a solar power station in a geosynchronous orbit 36,000 kilometres above ground. The electricity generated would be converted to microwaves or lasers and transmitted to a collector on Earth. If realized, it will surpass the scale of the Apollo project and the International Space Station and be the largest-ever space project."

An anonymous reader points out that a long held goal of keeping the Earth's average temperature from rising above 2 degrees Celsius might not be good enough. "A long-held benchmark for limiting global warming is 'utterly inadequate,' a leading U.N. climate scientist declared. Keeping the Earth's average temperature from rising past 2 degrees Celsius – a cap established by studies in the early 1970s – is far too loose a goal, Petra Tschakert, a professor at Penn State University and a lead author of an assessment report for the U.N.'s Intergovernmental Panel on Climate Change, or IPCC, said in a commentary published in the journal Climate Change Responses. Already, with an average increase of just 0.8 degrees Celsius, she wrote, 'negative impacts' are 'widespread across the globe.' Tschakert called for lowering the warming target to 1.5 degrees Celsius."

An anonymous reader shares this story that takes a look at some of the advances SpaceX is working on. "Getting a small group of human beings to Mars and back is no easy task, we learned at the recent GPU Technology Conference in San Jose hosted graphics chip and accelerator maker Nvidia. One of the problems with such a mission is that you need a very large and efficient rocket engine to get the amount of material into orbit for the mission, explained Adam Lichtl, who is director of research at SpaceX and who with a team of a few dozen programmers is try to crack the particularly difficult task of better simulating the combustion inside of a rocket engine. You need a large engine to shorten the trip to Mars, too....Not only do you need a lot of stuff to get to Mars and sustain a colony there, but you also need a way to generate fuel on Mars to come back to Earth. All of these factors affect the design of the rocket engine....As if these were not problems enough, there is another really big issue. The computational fluid dynamics, or CFD, software that is used to simulate the movement of fluids and gases and their ignition inside of all kinds of engines is particularly bad at assisting in rocket engine design. 'Methane is a fairly simple hydrocarbon that is perfectly good as a fuel,' Lichtl said. 'The challenge here is to design an engine that works efficiently with such a compound. But rocket engine CFD is hard. Really hard.'"

MTorrice writes: A foam composed of a polymer derived from crustacean shells may prevent more soldiers from falling victim to the most prolific killer on the battlefield: blood loss. Pressure is one of the best tools that medics have to fight bleeding, but they can't use it on severe wounds near organs. Here, compression could do more harm than good. First responders have no way to effectively dam blood flows from these non-compressible injuries, which account for the majority of hemorrhagic deaths. The new foam could help stop bleeding in these types of injuries. It relies on chitosan, a biopolymer that comes from processed crustacean shells. By modifying the chitosan, the developers gave the material the ability to anchor blood cells into gel-like networks, essentially forming blood clots. The researchers dispersed the modified chitosan in water to create a fluid they could spray directly onto noncompressible wounds.

An anonymous reader writes: A light bulb made from graphene — said by its UK developers to be the first commercially viable consumer product using the super-strong carbon — is to go on sale later this year. The dimmable LED bulb with a graphene-coated filament was designed at Manchester University, where the material was discovered in 2004. It is said to cut energy use by 10% and last longer owing to its conductivity. It is expected to be priced lower than current LED bulbs, which cost about £15 (~$22) each.

rtoz writes: A group of scientists in California have successfully created eye drops that temporarily enable night vision. They use mixture of insulin and a chemical known as Chlorin e6 (Ce6) to enable the user to view objects clearly in darkness up to 50 meters away. Ce6 is found in some deep-sea fish and often used to treat night blindness. The solution starts to work within an hour of being applied to the user's eyes, and lasts for several hours afterward. The test subject's eyesight returned to normal the next day. The organization Science for the Masses has released a paper detailing the experiment on their website.

schwit1 writes Because it has concluded that they make it impossible to have a fair competition for contracts, the Air Force has decided to phase out taxpayer subsidies to the United Launch Alliance (ULA). The specific amounts of these subsidies have been effectively buried by the Air Force in many different contracts, so we the taxpayers really don't know how much the are. Nonetheless, this decision, combined with the military report released yesterday that criticized the Air Force's over-bearing and restrictive certification process with SpaceX indicates that the political pressure is now pushing them hard to open up bidding to multiple companies, which in turn will help lower cost and save the taxpayer money.

schwit1 writes: Using the Hubble and Chandra space telescopes astronomers have discovered that dark matter is not only invisible to direct observation, it is invisible to itself! Quoting: "As two galactic clusters collide, the stars, gas and dark matter interact in different ways. The clouds of gas suffer drag, slow down and often stop, whereas the stars zip past one another, unless they collide — which is rare. On studying what happens to dark matter during these collisions, the researchers realized that, like stars, the colliding clouds of dark matter have little effect on one another. Thought to be spread evenly throughout each cluster, it seems logical to assume that the clouds of dark matter would have a strong interaction — much like the colliding clouds of gas as the colliding dark matter particles should come into very close proximity. But rather than creating drag, the dark matter clouds slide through one another seamlessly." The data here is on the very edge of reality, built on too many assumptions. We know that something undetected as yet is influencing the motions of galaxies, but what exactly it is remains completely unknown. These results only make the mystery more mysterious.

sciencehabit writes: In 2005, three computer science Ph.D. students at the Massachusetts Institute of Technology created a program to generate nonsensical computer science research papers. The goal was "to expose the lack of peer review at low-quality conferences that essentially scam researchers with publication and conference fees." The program — dubbed SCIgen — soon found users across the globe, and before long its automatically generated creations were being accepted by scientific conferences and published in purportedly peer-reviewed journals. But SCIgen may have finally met its match. Academic publisher Springer this week is releasing SciDetect, an open-source program to automatically detect automatically generated papers. SCIgen uses a "context-free grammar" to create word salad that looks like reasonable text from a distance but is easily spotted as nonsense by a human reader.

Rambo Tribble writes: An internal review commissioned by Air Force Secretary Deborah James has concluded that Air Force personnel tasked with evaluating SpaceX's certification treated it as a design review, going so far as to dictate organizational changes in the company. This was judged contrary to the intention of promoting a competitive environment. The report, prepared by former Air Force Chief of Staff General Larry Welch, concluded, "The result to date has been ... the worst of all worlds, pressing the Falcon 9 commercially oriented approach into a comfortable government mold that eliminates or significantly reduces the expected benefits to the government of the commercial approach. Both teams need to adjust."

Zothecula writes By cladding a living cell with graphene quantum dots, researchers at the University of Illinois at Chicago (UIC) claim to have created a nanoscale biomicrorobot (or cytobot) that responds electrically to changes in its environment. This work promises to lay the foundations for future generations of bio-derived nanobots, biomicrorobotic-mechanisms, and micromechanical actuation for a wide range of applications. "UIC researchers created an electromechanical device — a humidity sensor — on a bacterial spore. They call it NERD, for Nano-Electro-Robotic Device. The report is online at Scientific Reports, a Nature open access journal."

schwit1 writes In a report as well as at House hearings today the GAO reported that Northrop Grumman has denied them one-on-one access to workers building the James Webb Space Telescope. "The interviews, part of a running series of GAO audits of the NASA flagship observatory, which is billions of dollars overbudget and years behind schedule, were intended to identify potential future trouble spots, according to a GAO official. But Northrop Grumman Aerospace, which along with NASA says the $9 billion project is back on track, cited concerns that the employees, 30 in all, would be intimidated by the process." To give Northrop Grumman the benefit of the doubt, these interviews were a somewhat unusual request. Then again, if all was well why would they resist? Note too that the quote above says the cost of the telescope project is now $9 billion. If the project was "back on track" as the agency and Northrop Grumman claim, then why has the budget suddenly increased by another billion?

Let's kill the suspense right away by answering the title question, 'Probably not.' For one thing, according to interviewee Alfred Poor, the Apple Watch is in no way linked to the Apple Research Kit. Dr. Poor is editor of the Health Tech Insider website, so he follows this kind of thing more carefully than most people. And the Apple watch is not the only device mentioned in this video (or transcript, if you prefer reading to listening). If you want to ruminate about the possibility of direct mind control, for instance, you need to know about the Thync, whose vendor calls it 'A groundbreaking wearable device that enables you to shift your state of mind in minutes.' They say it 'induces on-demand shifts in energy, calm, or focus.' It even has a 'pleasure' setting. Crank that to 11 and you might happily spend your days prone, being fed by a drip and emptied by a catheter, moving only when an attendant turns you over to keep bedsores from developing -- not that you'll care if they do -- as you spend the rest of your life in an artificially-induced joyful stupor.

sciencehabit writes Today researchers unveiled the largest ever set of full genomes from a single population: Iceland. The massive project, carried out by a private company in the country, deCODE genetics, has yielded new disease risk genes, insights into human evolution, and a list of more than 1000 genes that people can apparently live without. The project also serves as a model for other countries' efforts to sequence their people's DNA for research on personalized medical care, says study leader Kári Stefánsson, deCODE's CEO. For example, the United States is planning to sequence the genomes of 1 million Americans over the next few years and use the data to devise individualized treatments.

coondoggie writes NASA officials today said they have picked the specific asteroid mission and offered new details for that mission which could launch in the 2020 timeframe. Specifically, NASA's associate administrator Robert Lightfoot said the Asteroid Redirect Mission (ARM) will rendezvous with the target asteroid, land a robotic spacecraft on the surface, grab a 4 meter or so sized boulder and begin a six-year journey to redirect the boulder into orbit around the moon for exploration by astronauts.
